IXimager file formats

ILook Investigator v8 and its disk-imaging counterpart, IXimager, offer three proprietary, authenticated image formats: compressed (IDIF), non-compressed (IRBF), and encrypted (IEIF). Although few technical details are disclosed publicly, IXimager's online documentation provides some insights: IDIF "includes protective mechanisms to detect changes from the source image entity to the output form" and supports "logging of user actions within the confines of that event;" IRBF is similar to IDIF except that disk images are left uncompressed; IEIF, meanwhile, encrypts said images.

For compatibility with ILook Investigator v7 and other forensic tools, IXimager allows for the transformation of each of these formats into raw format.
